Debian

Debian is a Linux distribution, that is widely used for desktop computers, however it's been gaining popularity as a server OS over the last few years too. It is really stable and safe, since fixes are released in a few days after a problem is discovered. Debian has a large support community, so if you have any questions or problems with the OS or with some of the 30,000+ packages it is equipped with, you'll be able to contact the developers straight away through email using special e-mail lists and receive a reply within 15-20 minutes. The Debian community supplies the best level of support possible, because your questions will be handled by the same people who created Debian in the first place, so they have a detailed knowledge of how their own system works. As the Operating System is free to use and distribute, no license costs will be added to your hosting fees and you will be able to modify the program code files and any other software which you install with no restrictions, in order to optimize the software environment for your Internet sites. Furthermore, Debian performs very well on any kind of hardware, as it is light and quick and does not require much memory.
